x=6

Step-by-step explanation:

to solve this equation, we need to isolate the variable (x).

to do this we must subtract both sides by 8.

doing this we get:

4x=24

now we need to divide both sides by 4:

x=6

that's the answer!

Which equation finds m given E, and C

Answers

Answer:

C

Step-by-step explanation:

E=mc^2

To find m, isolate m from the rest of the variables, E and C. Since m and c^2 are being multiplied, use the inverse of multiplication, division, to undo the multiplication.

E/c^2 = m.

Answer:

the slope is 3

Step-by-step explanation:

Answer:

m = -1/3

Step-by-step explanation:

You have the right idea with the rise and run. We have a run of 15 and a rise (or I guess in this case, a decline) of -5. Slope is rise over run:

-5/15 = -1/3

This means we have a slope of -1/3.

Alternatively, we could just the points and put them into the slope formula.

We have the points (0,25) and (15,20). We can substitute those values into the formula:

m = y₁ - y₂ / x₁ - x₂

m = 25 - 20 / 0 - 15

m = 5/-15

m = -1/3

Works all the same.

The cylindrical part of a architectural column has a height of 325 cm and a diameter of 30 cm. Find the volume of the cylindrical part of the column. Use 3.14 for π and round your answer to the nearest cubic centimeter if needed.

Answers

Answer:

[tex]V=229612.5\ cm^3[/tex]

Step-by-step explanation:

Given that,

The height of a cylinder, h = 325 cm

Diameter, d = 30 cm

Radius, r = 15 cm

We need to find the volume of the cylinder. The formula for the volume of a cylinder is given by :

[tex]V=\pi r^2h[/tex]

Putting all the values,

[tex]V=3.14\times (15)^2\times 325\\\\V=229612.5\ cm^3[/tex]

So, the volume of the cylinder is [tex]229612.5\ cm^3[/tex].

The function f(x) = 2x^2 + 3 represents the rate of a boat traveling with the current in miles per hour.The function g(x) = x+2 represents the time the boat traveled in hours. Solve (f x g) (2), and then interpret the answer (f x g)(2) = 15, the distance in miles the boat traveled

(F times G) (2) = 15, the distance in miles the boat traveled

(F time G) (2) = 15, the number of boats

(F times G) (2) = 44, the distance in miles the boat traveled

(F times G) (2) = 44, the number of boats

Step-by-step explanation:

Average speed = 400 miles per hour

Distance = 400t

t= 5

Total distance = 400t at t hours

Total distance when t = 5 hours

Total distance travelled = 400t

= 400 × 5

= 2,000 miles

Total distance travelled = 2,000 miles

The distance travelled by the B737-400 aircraft in 5 hours is 2,000 miles

The square root of a number is the number that, when multiplied by itself, gives the original number.

Given that,

The expression is 9 to the power of -1/2.

Now, it can be written as,

9 to the power of -1/2

   Suzi starts her hike at 220 feet below sea level. When she reaches the end of the hike, she is still below sea level at −107 feet. What was the change in elevation from the beginning of Suzi's hike to the end of the hike?


The change was____ feet.
 

Answers

Answer: 113 feet.

Step-by-step explanation: Even though Suzi was still below sea level at the end of the hike, she still climbed 113 feet higher.

-220 - (-107) = c-220 + 107 = c-113 = c

The change will be positive, though, because Suzi was climbing up, not down. Therefore the final answer is 113 feet.

Answer:

Step-by-step explanation:

Let sea level be our reference point.  Suzi starts at -220 ft and ends up at -107 ft.  The change in elevation is represented by x = |-220 ft - (-107 ft)|, or 113 ft.
